Subject: Security Implications of letting customers use their own kernel
Date: Wed, 15 Dec 2010 12:26:28 +0000 [thread overview]
Message-ID: <4D08B3F4.7020008@abpni.co.uk> (raw)
Hi Everyone,
What are the security implications of letting customers install their
own kernel?
In my own research, I have only seen things that would compromise their
own DomU. My main area on concern is to protect all the other DomUs.
An area of potential concern is if someone were to build a kernel that
enabled "No Execute" or "Disable Execution", could that compromise other
DomUs? Or would that just leave their DomU vulnerable to running
malicious code?
Anyone aware of anything else?
Thanks
